For the Function, Find the Average Rate of Change of F

Multiple Choice

For the function, find the average rate of change of f from 1 to x: $$\frac { f ( x ) - f ( 1 ) } { x - 1 } , x \neq 1$$
- $$f ( x ) = \sqrt { x + 35 }$$

A) $\frac { \sqrt { x + 35 } + 6 } { x - 1 }$

B) $\frac { \sqrt { x + 35 } + 6 } { x + 1 }$

C) $\frac { \sqrt { x + 35 } - 6 } { x + 1 }$

D) $\frac { \sqrt { x + 35 } - 6 } { x - 1 }$
